Attempts to smuggle drugs into Calgary earlier this month got stopped at the net, thanks to some eagle-eyed customs agents.

On Sept. 7, Canada Border Services Agency (CBSA) officers inspecting baggage at the Calgary International Airport took note of inconsistencies within a number of tennis balls stowed within a traveller's suitcase, said CBSA spokeswoman Elise Gaetz.

The traveller and his luggage — whom Gaetz says arrived on a fight that originated in India — was flagged for a closer inspection.
